rubber industry
Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanizing agent in natural rubber, synthetic rubber, and latex, and can also be used as a plasticizer and softener. Stearic acid needs to be added as an emulsifier in the production of synthetic rubber. When making foam rubber, stearic acid can be used as a foaming agent, and stearic acid can also be used as a release agent for rubber products.
Industrial stearic acid appears as white or slightly yellow particles or blocks, a mixture of stearic acid and palmitic acid, and contains a small amount of oleic acid with a slight fat odor.
